Item Conceptualization of "Southern” in Political Communication (With Special Reference to Simple Majority System)(19th Conference on Postgraduate Research, International Postgraduate Research Conference 2018, Faculty of Graduate Studies,University of Kelaniya, Sri Lanka, 2018) Gamage, D.Political Communication has originated with the origin of the world history is the idea of most of Intellectuals. With the origin of the democracy and political parties¸ Political Campaign has become more organized, systematic and a competitive process. Politicians have tried to gain public opinion going beyond advertising or marketing․ Political campaign has become a systematic process with the use of regionalism as an advantage in gaining public opinion. When analyzing election campaigns that have conducted so far, it has been confirmed that regionalism has used in political campaigns. In this research, the use of regionalism concept called “southern” by political members was studied. Further election campaigns of the candidates, which were conducted during 1947 to 1977 as simple majority system¸ were also studied using “Dinamina” and “Lankadeepa” newspapers and 40 interviewers were conducted in order to gather date. In particular, the campaign of Mr. C.P. De Silva was studied. Based on the analysis¸ this study has proven the hypothesis and strongly found that C.P De Silva has used “Southern regionalism concept” with their election campaigns. In addition to that, it has been concluded that this down south cast concept has used by him as a strategy to attract their voters. The opposite candidates have criticized the southern regionalism concept and down south cast concept but those who represented southern province have used those criticisms in a systematic way to win their election campaign․ Therefore¸ these said two concepts have been negatively compacted on opposite candidate election campaignsItem Radio “Dambana”: A new experiment of Community radio in Sri Lanka(Faculty of Graduate Studies, University of Kelaniya, 2015) Herath, D.B.; Rupasinghe, W.; Jayasekara, D.; Gamage, D.; Attanayaka, M.Sri Lanka is the first country which started the Community Radio station in Asia, as Mahawali Community Radio (MCR).But many researchers points out that it was not a proper way of establishing a community radio.(Jayaratne,2008).The rationale behind is that its name as ―community‖ but functioned as ―state owned‖. In 2010 the main MCR station Giradurukotte Community Radio, launched as Radio Dambana. It was transformed as community radio for Sri Lankan Vadda community mainly located in the area of Dambana. In this research we are trying to analyze the main functions of the radio dambana as a community radio. While doing this we are searching the sustainability of the station and its scope. We have used mix methods to collect data such as interviews field visits, content analysis of the programmes as primary data. To analyze the data we deployed the SWOT analysis as a tool. The findings suggest the format of radio dambana would need a shift of its functions to achieve the aims and objectives of the station.Item Spatial epidemiologic trends and hotspots of leishmaniasis, Sri Lanka, 2001-2018(Centers for Disease Control and Prevention (CDC), 2020) Karunaweera, N.D.; Ginige, S.; Senanayake, S.; Silva, H.; Manamperi, N.; Samaranayake, N.; Siriwardana, Y.; Gamage, D.; Senerath, U.; Zhou, G.;ABSTRACT: Leishmaniasis, a neglected tropical disease, is on the decline in South Asia. However, cases of cutaneous leishmaniasis have risen in Sri Lanka since 2001, and the lack of in-depth research on its epidemiologic characteristics hampers control efforts. We analyzed data collected from patients with cutaneous leishmaniasis in Sri Lanka during 2001-2018 to study temporal and geographic trends and identify and monitor disease hotspots. We noted a progression in case rates, including a sharp rise in 2018, showing temporal expansion of disease-prevalent areas and 2 persistent hotspots. The northern hotspot shifted and shrank over time, but the southern hotspot progressively expanded and remained spatially static. In addition, we noted regional incidence differences for age and sex. We provide evidence of temporally progressive and spatially expanding incidence of leishmaniasis in Sri Lanka with distinct geographic patterns and disease hotspots, signaling an urgent need for effective disease control interventions.

Spatiotemporal and risk factor analyses are useful for understanding transmission dynamics, spatial clustering and predicting future disease distribution and trends to facilitate effective infection control. METHODS: The nationwide clinically confirmed cutaneous leishmaniasis and climatic data were collected from 2001 to 2019. Hierarchical clustering and spatiotemporal cross-correlation analysis were used to measure the region-wide and local (between neighboring districts) synchrony of transmission. A mixed spatiotemporal regression-autoregression model was built to study the effects of climatic, neighboring-district dispersal, and infection carryover variables on leishmaniasis dynamics and spatial distribution. Same model without climatic variables was used to predict the future distribution and trends of leishmaniasis cases in Sri Lanka. RESULTS: A total of 19,361 clinically confirmed leishmaniasis cases have been reported in Sri Lanka from 2001-2019. There were three phases identified: low-transmission phase (2001-2010), parasite population buildup phase (2011-2017), and outbreak phase (2018-2019). Spatially, the districts were divided into three groups based on similarity in temporal dynamics. The global mean correlation among district incidence dynamics was 0.30 (95% CI 0.25-0.35), and the localized mean correlation between neighboring districts was 0.58 (95% CI 0.42-0.73). Risk analysis for the seven districts with the highest incidence rates indicated that precipitation, neighboring-district effect, and infection carryover effect exhibited significant correlation with district-level incidence dynamics. Model-predicted incidence dynamics and case distribution matched well with observed results, except for the outbreak in 2018. The model-predicted 2020 case number is about 5,400 cases, with intensified transmission and expansion of high-transmission area. The predicted case number will be 9115 in 2022 and 19212 in 2025. CONCLUSIONS: The drastic upsurge in leishmaniasis cases in Sri Lanka in the last few year was unprecedented and it was strongly linked to precipitation, high burden of localized infections and inter-district dispersal. Targeted interventions are urgently needed to arrest an uncontrollable disease spread.Item අර්බුද කළමණාකරන ක්රියාවලියේදී ජනමාධ්යය ක්රියාකාරීත්වය(SIDA/SAREC Research Library, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2016) Gamage, D.Item දේශපාලන ප්රචාරණ වැඩසටහන්හි සාර්ථක අසාර්ථකභාවය සඳහා ජන විඥානය හේතුවන ආකාරය(The Research Center for Social Sciences, Faculty of Social Sciences, University of Kelaniya, 2015) Gamage, D.Item මහජන මතය සහ පුවත්පත(Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2015) Gamage, D.
